Young and attractive Ann works in a Berlin drive-in cinema. One day, she meets an eloquent and charming estate agent, Bernie Kallmann, who Ann quickly falls in love with. Unknown to Ann, Bernie's apparent attraction towards her, as with many other women, is because Kallmann is a pimp and a significant member of the ring that controls all prostitution in the city.^[4]

When Bernie knows Ann's feelings for sure, he persuades her to work on the streets a prostitute.^[4] Bernie makes a big mistake, he falls in love with Ann. Now Kallmann, after he has pushed his beau into prostitution, tries to get Ann out of it. This causes massive conflicts with the rest of the pimp gang.

Tremper himself described Sperrbezirk as "A gruesome story of an naive country girl, which becomes a hooker out of love."^[5]

The Lexikon des internationalen Films summed the film up as "a draw between mischief, brutality and speculation fluctuating colportage. The implied dispute with prostitution is merely inadequate camouflage."^[6]
